subject of the King of Great Britain, 'resid Be -it known that I, HERMAN House, a

ing at Flindei's Buildings, Flinders street,

' f Melbourne, the State of Victoria, Co In- I nonw'ealthv of Australia, merchant, have lIlrented new land useful Improvements in Sprin g'Suspensioiis in Vehicles for-Absorb- ,ing' Road-Shocks, of which the followingis a specification;

My inven ion springsuspensions utilizable in vehicles,

" particularly those of the motor driven type si'ich as motor cars and lorries, whereby the shocks upon the" wheels "of the car shall :be

inore orles's absorbed v This invention is an improvement upon that for'wliichI applied for a patent in the United States of America on the 30th day of July, 1912, Serial Number 712,306. In that specification I described a spring suspension, arranged near to'- each wheel of the vehicle, ,consistingof two, leaf springs the J thick ends of which are clamped together and 'boredhorizontally and transversely to "receivea pinfl'upon the vehicle frame about "whichf thesaid "springs shall be capable,

within certain limits, I of turning, Both members of t h'espring flare in the same di- 80 tach'ed the onejto the vehicle frame through "rection and theendsor tips thereof are ata shackle or iink and the otherito a wheel l axle oraxle casing.-

In'the present invention, 1 use in the spring a springy supportresting on the axle and attached at one of it's ends in the clamped end of the spring and at its other end to the extremity of the'vehicle frame. have also shown a means 'for supporting the clamped Springs pivotally outside the springs which arrangement may be used" with or without the springy support as will be hereinafter ,dcscribed; a

In the accompanying drawing Figure l is a side elevation ofpart of the veh cle frame showing the flaring springs'co'mbined with the resilient horizontal supporting member.- Fig. 1 is a similar view of a difi'erentform of the invention. Fig. 2 is also a sideeleration of my invention wherein the flaring springs arepivotally'supported in brackets on the vehicle 7 main springs. Fig; 3 shows in front eleva tion a motor, carfitted with my'springsfas' in Figs-1, and Fig. 4 is a perspective ragrelates to improvements in frame at the back the together in the clamps orholdfasts 9. The

other ends or'tips of the springs 7 are at- .tached respectively'the-one totheframe 4 and the-other to a wheel axle or a-xle casing, the tip of the upper spring being loosely connected through the shackle .18 which is itself attached in like manner tothe frame,

while the tip of the lower springniembe'r will be attached to theaxlelQTbr totlie axle I ces1ng 12 The clamped springs are pivotally mounted-in the ve'hicle frame, or to a bracket de pending therefrom, on a pin 11 which pmects horizontally and transversely and provides a center about which the clamped springs may have a limited rotary-movement. The in 11 is preferably in the .lower end of; the link 15 which is itself pivotally hung in the base plate 15"- and together therewith constitutes a jointed or flexible bracket. I I In Fig. 1 I have shown the front springs 7 pivoted to such a bracket and containing the supporting resilient member 6 which is tal, mayhave-a slight camber, so as-to-present a slightly convex surface to the axle 12 In re, the member 6 is composed of butone -leaf,-but it is reinforcedatjthe axle by a short leaf l6. .To adapt the member 6 to the axle casing 12'"- I secur'e'to the casing a tabular clamp -17 upon which 6- Will be secured'cleai" of the adjacent parts of the suspension. Phe function of the spring 6 is toact asza support or torque to the axle, to give extra lateral stability and to assist to carry' the load orto give an extrajdamping effect by acting as a snubber'. Referring now to Fig. 2 I may "avoid transversely piercin the clamped ends of the springs-by exten 'backward'fiom the clamps 9 one or more of theiinner. leaves of the springs 7 and 'adapting'the' same to a pivotal mounting on thebrackets 15.

I preferably utilize with this spring the torque rod 13 between a point on the axle 1 for axle casing and the frame'of the vehicle, but-this may be dispensedwith' ifjthe member 6 and theflexible bracket of Fig.- 1 is employed in combination with the extended leaves. 'springs 7 with the pivoted bracket 15, it may not be necessary-to use a; shackleorlink at the point of connectionof them'ember 6 with-the frame .4,but" when thebracket is ifigid on the frame'as' in the case of the rearwheel I) the'spring6 must be shackled to the frame as indicatedin the figure. j

The use and disposition of the pivoted brackets and shackles withthe springs .will in each-casedepend'to some extentupon the design offchassisto which-they aref fitted,

the'reon atts eonnectionfwith the clamped and the spring 6- ma be hinged,'if"nec'essary, as shownat 18, to avoid undue strain The pos tion of thl11nged or flexible, bracket relatively to '-'the""sprin'g need notnecessarily be as shown inFig. 1-, as it may, for instance', be p'lacedbehind the spring in .fth'e position of the rigid'bracket of Fig.2; Insuch case the inner leaves .of the spring an the springymember 6 wouldbe secured above, disposition is made the torque rod 13 will of course; not be required.

jHavin'gnow described my invention what. I I claim as newt-and desire to secure by Let- 11 In springsuspensions of the kind in dicated, the combination witha pair of leaf springs having their thick ends clamped togather "and pivotally connected, through suitable means, tothe frame of the vehlcle while'theirtip's flaringly project 1n the same.
